A constellation is a group of stars or constellations of stars that seemed connected to form a specific configuration. In three-dimensional space, which we observe most stars do not have a relationship with one another, but it can look like clusters at the ball the night sky. Humans have a very high ability to recognize patterns and throughout history have grouped stars that appear adjacent to the constellations. The composition is not an official constellation, which is known widely by the community but not recognized by astronomers or the International Astronomical Society, also called asterisma. The stars in the constellation of stars or which have rarely asterisma astrophysics; they just happen to appear close together in the sky just visible from Earth and is usually very far a part.

The grouping of stars into constellations is actually quite random, and different cultures will have different constellations, although some are very easily recognizable usually often found, such as Orion or Scorpius. The International Astronomical Society has divided the sky into 88 official constellations with clear boundaries, so that every direction only owned by one constellation only. In the hemisphere (hemisphere) north, most of the star constellations are based on the Greek tradition, passed down through the Middle Ages, and contains the Zodiac symbols. Various other patterns that do not officially exist together with the constellations and called asterisma, such as the Plough also known in the United States as the Big Dipper and Little Dipper. In addition, there are 88 modern constellations based on the breadth of the sky, measured in square degrees.

Liputan6.com, Wellington: Ten new planets “floating” through the galaxies found in an international team of astronomers led by New Zealand scientists. Tenth Jupiter-sized planet that is a new discovery in the history of the Bima Sakti Galaxy. The invention uses software developed by computer scientists Massey University, Wellington, Australia. “They are giant planets in our galaxy, about the size of Jupiter. It turned out that this submarine is the tenth planet somewhere in between us and the stars,” said Ian Bond, an Astro Physics, recently. The planets were believed to be located about two-thirds of the center of the galaxy, located about 25,000 light-years. If they are visible to the naked eye, the planets would be pitch black, because they do not emit light. This new planet could be removed from the solar system since the meeting of gravity close to other planets or stars. Most likely the new planets grow from collapsing ball of gas and dust, but do not have the mass to ignite the fuel and produce starlight alone. These findings led the researchers hope that the free floating planetary sized Earth could support life. Although until now the possibility was small, such planet yet detected.
